ABSTRACT
the mechanical properties of a welding construction depend on several factors such as air humidity during welding. A test is required to produce good quality and safety from a welding construction. From the tests performed on a welding construction, mild carbon steel material (soft carbon steel) is used. The welding is carried out by means of electrode welded electrode welding electrodes, with type E-7016 electrode type, flux-type low powder iron hydrogen, while different air humidity for each specimen, each of which: Test specimens I with air humidity + 50% ; Test specimen I with air humidity + 60%; Test specimen I with air humidity + 80%. It is known that the air humidity will raise the water content in the electrode, resulting in the decreasing of mechanical properties of welding construction. So to produce good quality and safety from the welding construction, it is necessary to have a large air humidity restriction or special subscription to the electrode to be used.
